How effective is Nizoral shampoo in the treatment of hair loss?

There is NO shampoo that can truly claim it is a "treatment" for hair loss.It does not work.  It is not a "heavy hitter" or even a "baby hitter".It does not maintain hair or keep hair from falling out.It may be a good shampoo and many seem to like it because it makes your scalp feel tingly.Ketoconazole theoretically has anti-androgen properties but in clinical use, it has negligible effects on hair.You can make yourself believe it has some DHT blocking / anti-androgen properties and spend the money to try it.  After all, if it costs so much, there must be some truth to the claim, right?  

I have tried this for many years and do not see much benefit.  There is no harm to try though.  Best, Dr. Emer.

Nizoral or ketokonazol is an anti fungal medication with some effects on maintaining hair.  The result of it has been compared to minoxidil and it has been documented that similar results could be expected form them.  Having said that the route of use for shampoos makes their usefulness more limited since we wash and rinse our scalp and do not leave them long enough for them to become absorbed from the skin level.

Ketoconazole is not a DHT blocker.  Many men use it for hair loss but it really will not treat hair loss successfully

There Are two FDA approved treatments for  hair loss which are minoxidil and propecia.  However, there are some shampoos, vitamins and other remedies that help with the maintainance of the quality of the hair, however there are no studies that confirm their importance in preventing hair loss.  If you have tried nizoral and it helps maintainin your hair then go ahead and use it, but do not expect re growth or regeneration of lost hair.
